Silica Epoxy Thickener can be used alone or combined with other fillers to achieve the desired properties. For example, blend into mixed resin/hardener along with TotalBoat Glass Microballoons (sold separately) to allow easy sanding when fairing. Or, combine with TotalBoat Milled Glass Fibers (sold separately) for added strength and sag resistance.

TotalBoat fillers can be used with either epoxy or polyester resins to change the resin properties for various uses, such as bulking out the resin or making it easy to sand. Because fillers can affect the pot life of a resin, create a small trial batch first to determine how much working time you’ll have.
